“Whatever, therefore, wicked princes plan against us, God Himself permits to be done. And yet most unjust persecutors, to whom the name of God was a subject of reproach and mockery, must not think that they will escape with impunity, because they have been, as it were, the ministers of His indignation against us. For they will be punished with the judgment of God, who, having received power, have abused it to an inhuman degree, and have even insulted God in their arrogance, and placed His eternal name beneath their feet, to be impiously and wickedly trampled upon. On this account He promises that He will quickly take vengeance upon them, and exterminate the evil monsters from the earth. But He also, although He is accustomed to avenge the persecutions of His people even in the present world, commands us, however, to await patiently that day of heavenly judgment, in which He Himself will honour or punish every man according to his deserts. Therefore let not the souls of the sacrilegious expect that those whom they thus trample upon will be despised and unavenged. Those ravenous and voracious wolves who have tormented just and innocent souls, without the commission of any crimes, will surely meet with their reward. Only let us labour, that nothing else in us may be punished by men but righteousness alone: let us strive with all our power that we may at once deserve at the hands of God the avenging of our suffering and a reward.”

“Having demanded from servants so great virtue, for it is great virtue to adorn the doctrine of our God and Saviour in all things, and charged them to give no occasion of offense to their masters, even in common matters, he adds the just cause, why servants should be such: "For the grace of God, that bringeth salvation, hath appeared." Those who have God for their Teacher, may well be such as I have described, seeing their numberless sins have been forgiven to them. For you know that in addition to other considerations, this in no common degree awes and humbles the soul, that when it had innumerable sins to answer for, it received not punishment, but obtained pardon, and infinite favors. For if one, whose servant had committed many offenses, instead of scourging him with thongs, should grant him a pardon for all those, but should require an account of his future conduct, and bid him beware of falling into the same faults again, and should bestow high favors upon him, who do you think would not be overcome at hearing of such kindness? But do not think that grace stops at the pardon of former sins-it secures us against them in future, for this also is of grace. Since if He were never to punish those who still do amiss, this would not be so much grace, as encouragement to evil and wickedness. "For the grace of God," he says, "hath appeared, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present world; looking for the blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ." See, how together with the rewards he places the virtue. And this is of grace, to deliver us from worldly things, and to lead us to Heaven. He speaks here of two appearings; for there are two; the first of grace, the second of retribution and justice. "That denying ungodliness," he says, "and worldly lusts." See here the foundation of all virtue. He has not said "avoiding," but "denying." Denying implies the greatest distance, the greatest hatred and aversion. With as much resolution and zeal as they turned from idols, with so much let them turn from vice itself, and worldly lusts. For these too are idols, that is, worldly lusts, and covetousness, and this he names idolatry. Whatever things are useful for the present life are worldly lusts, whatever things perish with the present life are worldly lusts. Let us then have nothing to do with these. Christ came, "that we should deny ungodliness." Ungodliness relates to doctrines, worldly lusts to a wicked life. "And should live soberly, righteously, and godly in the present world." Dost thou see, what I always affirm, that it is not sobriety only to abstain from fornication, but that we must be free from other passions. So then he who loves wealth is not sober. For as the fornicator loves women, so the other loves money, and even more inordinately, for he is not impelled by so strong a passion. And he is certainly a more powerless charioteer who cannot manage a gentle horse, than he who cannot restrain a wild and unruly one.”

“But there is a great and general fasting, which is perfect fasting, to abstain from the iniquities and illicit pleasures of the world: "that, denying ungodliness and worldly desires, we may live soberly and justly and godly in this world." What reward does the apostle add to this fasting? He continues and says, "Looking for that blessed hope and the manifestation of the glory of the blessed God and Savior, Jesus Christ." Therefore, in this world we celebrate, so to speak, a Lent of abstinence when we live well, when we abstain from iniquities and illicit pleasures. But because this abstinence will not be without a wage, we look for "that blessed hope." In that hope, when reality shall have come to pass from hope, we shall receive a denarius as a wage.”

“Paul must receive, embrace and observe, without any reserve, those commandments of the law which help to form the character of the faithful, such as that "denying ungodliness and worldly desires, we should live soberly and justly and godly in this world" and "Thou shalt not covet," chosen by the apostle as the part of the law worthy of the greatest commendation; and also the commandments about loving God and our neighbor, as set forth in the law without any figure or mystery.… But whatever progress he makes in them he must not attribute it to himself but to "the grace of God by Jesus Christ our Lord." Letters 196.2.8.Fulgentius of Ruspe: The apostle Paul exclaims in a similar way: "Be imitators of God as his dear children." What will we reply to these words, brethren, or what excuse will we be able to have? If someone tells you that you should imitate the powers which our Lord exercised, there is a reasonable excuse for you, because not everyone is given the grace to exercise those powers and to work miracles. But to live piously and chastely, to preserve charity with all men, with God's help is possible for everyone.”

“Above, the Apostle instructed Titus how he should teach slaves and free men, and he concluded, as it were, with a reason, namely that the doctrine of Christ might be adorned; here, assigning the full reason for what was said, he explains what he said by way of good conduct. And first he sets forth the grace and teaching of Christ; second he leads him to the preaching of grace, at the place "these things speak." Again, first he sets forth the appearing of grace; second its instruction, at "instructing us"; third its operation, at "who gave." Now it must be known that grace implies mercy, because grace concerns that which is given freely, and what is given as a grace is given mercifully. But mercy was always in God, yet formerly it lay hidden with regard to men. Ps. 35:6: "Lord, your mercy is in heaven." For before Christ, all, however just they were, were under condemnation, but when Christ the Son of God assumed flesh, grace appeared. 1 Tim. 3:16: "And manifestly great is the mystery of piety, which was manifested in the flesh." Ps. 79:2: "You who sit upon the Cherubim, show yourself." But the more powerful someone is, the more his grace is desired. Hence the grace of God is to be desired; and this is what he says: "the grace of God." And this for the sake of saving, hence he says "and of our Savior." Is. 51:8: "But my salvation shall be forever." But this grace is not set forth to one people only, the Jews, as formerly, but to all men. Is. 40:5: "All flesh shall see together that the mouth of the Lord has spoken." Is. 52:10: "And all the ends of the earth shall see the salvation of our God." 1 Tim. 2:4: "He wills all men to be saved." And it can be said that at the nativity of Christ this grace appeared in two ways. In one way, and first, because through the greatest grace of God he was given to us. Hence, although his conception is the operation of the whole Trinity, it is nevertheless attributed especially to the Holy Spirit, who is the principle of graces. And this grace appeared to all men, and especially to the man Christ. Jn. 1:14: "full of grace and truth." From this grace, secondly, the instruction of the human race followed; because before Christ the world was in ignorance and heresy. Is. 9:2: "The people who walked in darkness have seen a great light." Hence he says "instructing us," namely as a man instructs a son. Now he has instructed us concerning two things, because two things are necessary for man, namely good work and right intention. First he shows how Christ instructed us concerning the first; second, concerning the second, at "awaiting." He says therefore: "that denying ungodliness and worldly desires." It should be noted that he says "ungodliness and worldly desires," because all sins either consist in those things which are directly against God, which are called sins of ungodliness. For piety, properly speaking, is that according to which we honor our parents and our fatherland. But because God is our principal father, therefore piety pertains to the worship of God. Job 28:28, according to another text, where we have it thus: "behold, the fear of the Lord, that is wisdom," it is found: "behold, piety, that is wisdom." And therefore sins against God are said to be ungodliness. Rom. 1:18: "For the wrath of God is revealed from heaven upon all ungodliness," and there he speaks of idolatry. Or they consist in the abuse of temporal things, and these are worldly desires. Now the saeculum is a space measuring the period of things. Hence by "worldly things" are understood worldly things, and all sins which are committed against one's neighbor, or against oneself, through the abuse of these. Then, when he says "soberly," etc., he shows what good we should do. And he says "soberly" with respect to oneself; "justly," with respect to one's neighbor; "piously" with respect to God. "Soberly" with respect to oneself, as it were measuredly; for bria is a measure, and this is when a man uses external things and his own passions with the measure of reason. Hence sobriety is taken for any measured use of external things and of extrinsic passions. Wis. 8:7: "For she teaches sobriety and wisdom and justice and virtue, than which nothing is more useful in life for men." "Justly" with respect to one's neighbor. Ps. 10:8: "The Lord is just and has loved justice." "Piously" with respect to God. 1 Tim. 4:7: "Exercise yourself unto piety." Then, when he says "awaiting the blessed hope," he instructs him concerning the end, which consists in two things, namely in the glory of the soul at death; the other in the glory of the body, at the coming of Christ. Jn. 5:28: "The hour comes in which all who are in the tombs shall hear the voice of the Son of God," et cetera. As to the first he says "awaiting the blessed hope," against those who place the end of man in the act of the virtues in this life. But this is not true, because even if we live soberly and piously and justly, we are still awaiting. Job 7:1 and 14:6: "as a hireling are his days." Is. 30:18: "blessed are all who wait for him." And therefore he says "awaiting the blessed hope." Which can be understood in two ways: either because it is a hope concerning beatitude; or because the awaiting itself makes them blessed. As to the second he says "and the coming of the glory of the great God, and of our Savior Jesus Christ," namely through whom our bodies will rise again. For he who loves a friend awaits him with desire. 2 Tim. 4:8: "and not only to me, but also to those who love his coming." Lk. 12:36: "you like men awaiting their lord." And he says "coming of glory," because the first coming was one of humility. Phil. 2:8: "he humbled himself," et cetera. Mt. 11:29: "learn from me, because I am meek and humble of heart." And that one will be of glory, because his divinity will become known to all. Lk. 21:27: "and then they shall see the Son of Man coming in the clouds with great power and majesty." And he says "of the great God," against Arius, who said the Son was not equal to the Father. And rightly "great," because it is said in Rom. 9:5: "who is above all, God blessed forever." 1 Jn., last chapter: "that we may be in his true Son," et cetera. Again, he is Savior. 1 Tim. 2:3: "For this is good and acceptable before God our Savior, who wills all men to be saved," et cetera. Because he came for this, and this his name signifies. Mt. 1:21: "for he shall save his people from their sins." And he adds "Christ," namely he who is anointed, in which is understood the union of divinity to humanity. For some are said to be united; but not in such a way that they have the essence of divinity united to them, but because they participate in something of it; but to Christ divinity is united. Ps. 44:8: "God, your God, has anointed you," et cetera. Then, when he says "who gave himself," the operation of grace is shown. And first he shows the benefit of the grace of his passion; second the fruit of the passion, at "that he might redeem us." He says therefore: I say that he is our Savior, and how? Because "he gave himself for us." Eph. 5:2: "walk in love, as Christ also loved us, and delivered himself up for us, an offering and a sacrifice to God." Its fruit is called liberation and sanctification. Liberation, when he says "that he might redeem us from all iniquity." Jn. 8:34: "whoever commits sin is a slave of sin." For the first man, through his own sin, was brought into the slavery of sin, from which slavery he was inclined to another sin; but Christ made satisfaction through his passion; and therefore we are redeemed from slavery. Is. 43:1: "do not fear, for I have redeemed you," et cetera. And not only from the original, but from all which one has added by one's own will. Sanctification is set down as a good, when he says "that he might cleanse for himself a people," that is, that he might sanctify a people, namely so that we might be his people, that is, consecrated to him. 1 Pet. 2:10: "who once were not his people, but now are his people." "Acceptable," namely to God through right faith and intention. Prov. 14:35: "an understanding servant is acceptable to the king." Or "acceptable," that is, peculiar. Deut. 7:6: "the Lord your God has chosen you that you may be to him a peculiar people." But it is also necessary that there be good works outwardly, hence he says "a follower of good works." Rom. 13:3: "do good, and you will have praise from it." Gal. 6:9: "and let us not fail in doing good." Then, when he says "these things speak," etc., he leads him to the preaching of grace, and concerning this he does two things; for first he exhorts him to preach; second he instructs him in the manner of preaching, at "with all," et cetera. He says therefore: speak the things that pertain to what is to be believed, exhort to the things that are to be done. 1 Thess. 2:3: "our exhortation was not from error, nor from uncleanness, nor in deceit." Rebuke those who do evil. 1 Tim. 5:20: "rebuke those who sin before all." And this "with all authority," that is, with authority, because he speaks as an instrument, or minister, of God. And therefore with confidence in the divine authority. Yet in exhorting one must sometimes speak with entreaty, considering one's own weakness. Prov. 18:23: "the poor man speaks with entreaties"; and sometimes with command, considering the authority committed to one. 2 Cor., last chapter: "do you seek a proof of him who speaks in me, Christ?" Or with gentleness toward the good, with authority toward the obstinate. But he needed to be admonished also that he should rebuke with authority, because he was naturally meek. 1 Tim. 4:12: "let no one despise your youth."”

“Who gave himself for us,.... Not another, or another's, but himself; not merely his own things, but his own self; not the world, and the riches of it, not gold and silver, and such like corruptible things, as the price of redemption; not the cattle on a thousand hills for sacrifice; not men nor angels, but himself; all that belong to him, all that is near and dear, his name, fame, credit, and reputation; his time, strength, and service: all the comforts of life, and life itself; his whole manhood, soul, and body, and that as in union with his divine person; which he gave into the hands of men, and of justice, and to death itself, to be a ransom price of his people, and for a propitiation and sacrifice for their sins, to be paid and offered in their room and stead: not for all mankind, but for many; for us, for all the elect of God, for the church; and who are represented when he gave himself, or died for them, as ungodly, sinners, and enemies: this was a free and voluntary gift, and is an unspeakable one; who can say all that is contained in this word "himself?" it is an instance of the greatest love, of love that passeth knowledge; God, because he could swear by no greater, swore by himself; and Christ, because he could give no greater gift, nor any greater instance of his love, gave himself, for the following ends and purposes: that he might redeem us from all iniquity: sin brings into bondage and, slavery, redemption is a deliverance from it; sin binds guilt upon the sinner, and lays him under obligation to punishment, and renders him liable to the curse and condemnation of the law; Christ was made sin, and a curse for his people, that he might redeem them from both, and deliver them from the punishment due to sin; which he has done by bearing it in his own, body on the tree, whereby he has redeemed them from all iniquity, that so it shall not be their ruin, or they come into condemnation on account of it; even from original sin, and from all actual transgressions; from all which his blood cleanses, and his righteousness justifies, and which God, for his sake, freely and fully forgives. Christ was called to this work by his Father, to which he agreed; and the plan of redemption being drawn in the everlasting council, and the whole adjusted and fixed in the covenant of peace; promises and prophecies were given out of it, and in the fulness of time Christ was sent, and came to effect it; and he has obtained eternal redemption for us, through the price of his own blood, which could have never been wrought out by any creature; and wherein all the divine perfections are glorified and is a plenteous and complete one; it includes in it, or connects with it, the blessings of justification, peace, pardon, adoption, and eternal life. It follows as another end of Christ's giving himself, or what is a branch of redemption, or consequent upon it, and purify unto himself a peculiar people, zealous of good works; all mankind are filthy and unclean by nature, in all the powers and faculties of their souls; nor can they cleanse themselves from their impurity of flesh and spirit, by anything that they can do: Christ has a peculiar people among these, a church whom he loves, and for whom he has given himself, that he might sanctify and cleanse them from their sins; which he has done by shedding his blood for them, and washing them in it, which cleanses from all sin, and he has purified them unto himself, for his own use and service, for his pleasure and delight, and to his glory; that they might be a proper habitation for him now; and that they might be made ready for him, to have the marriage between, him and them consummated; and that they might be presented to himself a glorious church, without spot or wrinkle, and be with him, both in the new Jerusalem state, into which nothing that defiles, or is defiled, enters, and in heaven, to all eternity. Now these people, for whom Christ has given himself, and whom he has redeemed and purifies, are a "peculiar people"; for whom Christ has a peculiar love, in whom he takes a peculiar delight, and to whom he grants peculiar nearness to himself, and bestows peculiar blessings on them, and makes peculiar provisions for them, both for time and eternity; these are Christ's own, his possession, his substance, what he has a special right to by his Father's gift, his own purchase, and the conquest of his grace; and they are a distinct and separate people from all others, in election, redemption, effectual calling, and in Christ's intercession, and will be in the resurrection morn, at the day of judgment, and to all eternity; and they are, as the word also signifies, an excellent and valuable people; they are Christ's portion and inheritance; they are his peculiar treasure, his jewels, whom, as such, he values and takes care of. The Syriac version renders it, "a new people". And they who are redeemed and purified by Christ, through the power of his grace upon them, become a people "zealous of good works"; not in order to their justification and salvation, but in obedience to the will of God, and to testify their subjection and gratitude to him, and for his honour and glory, and for the credit of religion, and the good of men, These not only perform them, but perform them from principles of truth and love, and with a zeal for the glory of God, and the honour of his Gospel; and with an holy emulation of one another, striving to go before, and excel each other in the performance of them.”

“Teaching us, that, denying, etc. - Παιδευουσα· Instructing us as children are instructed. Christ is the great teacher; and men, in order to learn, must become his disciples - must put themselves under his tuition, and learn of him. Denying ungodliness - Ασεβειαν· All things contrary to God; whatever would lead us to doubt his being, deny any of his essential attributes; his providence or government of the world, and his influence on the souls of men. Every thing, also, which is opposed to his true worship; theoretical and practical atheism, deism, and irreligion in general. Worldly lusts - Such desires, affections, and appetites, as men are governed by who have their portion in this life, and live without God in the world. Gluttony, drunkenness, lasciviousness, anger, malice, and revenge; together with the immoderate love of riches, power, and fame. We should live soberly - Having every temper, appetite, and desire, under the government of reason, and reason itself under the government of the Spirit of God. Righteously - Rendering to every man his due, injuring no person in his body, mind, reputation, or property; doing unto all as we would they should do to us; and filling up the duties of the particular stations in which it has pleased God to fix us, committing no sin, omitting no duty. And godly - Ευσεβως. Just the reverse of what is implied in ungodliness. See above. In this present world - Not supposing that any thing will be purified in the world to come that is not cleansed in this. The three words above evidently include our duty to God, to our neighbor, and to ourselves. 1. We are to live soberly in respect to ourselves. 2. Righteously in respect to our neighbor. And 3. Godly, or piously, in respect to our Maker.”

“Teaching--Greek, "disciplining us." Grace exercises discipline, and is imparted in connection with disciplining chastisements (Co1 11:32; Heb 12:6-7). The education which the Christian receives from "the grace" of God is a discipline often trying to flesh and blood: just as children need disciplining. The discipline which it exercises teaches us to deny ungodliness and worldly lusts, and to live soberly, righteously, and godly, in this present world (Greek, "age," or course of things) where such self-discipline is needed, seeing that its spirit is opposed to God (Tit 1:12, Tit 1:16; Co1 1:20; Co1 3:18-19): in the coming world we may gratify every desire without need of self-discipline, because all desires there will be conformable to the will of God. that--Greek, "in order that"; the end of the "disciplining" is "in order that . . . we may live soberly," &c. This point is lost by the translation, "teaching us." denying . . . lusts-- (Luk 9:23). The Greek aorist expresses "denying once for all." We deny "worldly lusts" when we withhold our consent from them, when we refuse the delight which they suggest, and the act to which they solicit us, nay, tear them up by the roots out of our soul and mind [ST. BERNARD, Sermon 11]. worldly lusts--The Greek article expresses, "the lusts of the world," "all worldly lusts" [ALFORD], (Gal 5:16; Eph 2:3; Jo1 2:15-17; Jo1 5:19). The world (cosmos) will not come to an end when this present age (aeon) or course of things shall end. live soberly, righteously, and godly--the positive side of the Christian character; as "denying . . . lusts" was the negative. "Soberly," that is, with self-restraint, in relation to one's self: "righteously" or justly, in relation to our neighbor; "godly" or piously, in relation to God (not merely amiably and justly, but something higher, godly, with love and reverence toward God). These three comprise our "disciplining" in faith and love, from which he passes to hope (Tit 2:13).”
